This is a Keil MDK-ARM project, containing a Profibus DP firmware wich is tailored to compile with Keil uVision. It consists of a firmware to create Profibus DP slave devices with the VPC3+S network controller, provided by the vendor Profichip, and an application.
The firmware source code is modified such that is can be compiled in Keil.
The project generates code for STM32F103C8T6 microcontroller.
The STM32 and the VPC3+S can be used as a Profibus DP interface.
Microcontroller and network controller communicates via SPI. Routines implemented in vpc3.c
In main() lies a test application sending some irrelevant data to a master device hanging on the same DP network. It also capable of receiveing 2 bytes data and display it on a character LCD screen.
